PAINT-SPRAYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 728,439, dated May 19, 1903.

Application filed March 5, 1901- Serial No. 49,704. (No modelfl T0 at whom it may concern.-

Be it known that I, REGINALD W. BIRD, of Boston, in the county of Sufiolk and State of Massachusetts,have invented certain new and useful Improvements in Paint-Spraying Apparatus, of which the'following is a specification.

This invention relates to an apparatus for spraying paint, calcimine, or other preparation upon Walls or ceilings; and its object is to provide a device which shall be readily portable or capable of being easily moved to different localities or positions on a floor, but having provisions whereby the weight of an operator may be utilized to anchor the apparatus to the floor during the operation or manipulation thereof.

The invention has for its further object to provide means for efiectively distributing or spraying the paint or other preparation upon the surface to be treated.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation illustrating my device and the manner of its operation. Fig. 2 represents a plan View of the apparatus. Fig. 3

1 represents a side elevation with a portion of the operators platform broken away. Fig.

4 represents a rear elevation, partly in section and with the operators platform removed. Fig. 5 represents a side elevation showing the operators platform and its manner of attachment to the pump-platform. Fig. 6 represents a perspective view showing the means for connecting the platforms. Fig. 7 represents a detail section of the strainer covering the outlet from the paint-supply tank. Fig. 8 represents a longitudinal sectional View of the spraying-nozzle- Fig. 9 represents a section on the line 9.9 of Fig. 8.

The same reference characters indicate the same parts in all of the figures.

In the drawings, 1 represents a platform, which I herein term the pump-platform, on which are mounted a supply-tank 2, adapted to .contain the paint or other preparation to be sprayed, and a pump 3, which is here shown as a double force-pump, but which may be of any desired pattern, such pump having a long operating lever or handle 4., a suction-pipe 5, connecting it with the supplytank 2, a flexible discharge pipe or hose 6,

be operated by two people, one of whom operates the pump while the other handles the be experienced in doing so because of the lack of stability of the platform, due to the moveters 10. vide means for securin gor anchoring the platform to the floor during the period of its operation, such means being preferably constructed so as to be rendered quickly operative or inoperative. In the drawings I show 'erator is caused to secure or anchor the pumpplatform to the floor during the period of its operation, my invention, however, notbeing limited to the exact devices or means herein shown.

sion of the pump-platform 1, but is detachably secured thereto and supported thereon at one end by a device which is shown clearly in Fig. 6 as consisting of a bar secured to projecting ends 12 12, which constitute looking members, and two upwardly-projecting hooks 13 13, secured to the. rear edge of. the pump-platform 1 and adapted to receive the projecting bar ends 12 12, the attach mentand detachment being performed by 'a vertical At the outer end of the operators platform 11 is a rigid or non-yielding leg or support 14, which rests upon the floor when the platform 11 is, operatively positioned. Fig. 1 shows the manner of operating the pumping part of theapparatus. The upper end of the pumpoperating handle atis arranged to swing partly over the platform 1], so that an operator ments of the platform permitted by the cas-' movement of the front end ofplatform 11.

standing on the platform can manipulate said and an air-chamber 7, provided with a pressure-gage 8.- The apparatusis designed to discharge-hose 6 and directs the spray which attempt to operate the pn mp 3,difliculty would i p It is accordingly desirable to pronovel means whereby the Weight of the opp 11 indicates an operators platform, which forms a lateral continuation or exten the front edge of the platform 11 and having pump-handle. The weight of the operator standing on platform 11 causes a heavy pressure or frictional contact between the nonrolling support 14 and the floor, which serves to anchor pump-platform 1 and prevent it from moving about while the pump is being operated. When the operators platform 11 is relieved of the persons weight, the apparatus may then be shifted about the floor without removing the platform 11, though this operation is rendered easier and the device is made more compactif said platform 11 be removed while the device is being shifted.

The inlet end of the suction-pipe 5 within the supply-tank 2 is equipped with a flaring cap or end piece 15, provided with a perforated strainer 16. Said suction-pipe also has a cock or valve 17, whereby the tank may be shut off from the pump whenever desired.

At the outer end of the hose 6 is a section of rigid piping 18, which the operator grasps in directing the spraying-nozzle, said section having at its inner end a valve 19 and at its outer end the spraying-nozzle 9. The con struction of the latter is shown in detail in Figs. 8 and 9. Its casing includes an inner chamber 20, having an inlet branch 21, into which the end of pipe-section 18 is screwed, and an outer chamber22. The outerandinner chambers are separated bya partition 23, having a series or group of perforations 24 24, here shown as three in number, and the outer wall of said chamber is provided with a single discharge-aperture 25, located opposite the middle of the group of apertures 24 24. By this arrangement the paint is distributed in a spreading stream or spray. At the opposite end of the casing from the perforated partition 23 is a clean-cut aperture 26, normally closed bya screw-plug 27, which may be removed to give access to the interior of the nozzle-casing and permit the latter to be cleaned out without requiring the removal of the whole nozzle from the pipe-section 18. By the use of my improved apparatus the spraying of paint or other liquid may be carried on with great facility. The containing vessel or reservoir 2 is open at the top, so that the paint or other preparation may be stirred from time to time to prevent the settling of its heavier ingredients and so that it may be easily refilled. It at any time it should be desired to disconnect the pump from the tank to clean the pump or for any other purpose, this may be etfected after first turning off the valve 17 by disconnecting a coupling or union 28, located in the suctionpipe 5 between the pump 3 and valve 17, and

then, if necessary, shifting the tank 2 or removing it from the platform.

I claim- 1. Asprayingapparatus comprisingapump having operating means and rolling supporting means for engaging the floor, and an operators foot-platform slightly elevated above the floor-level and laterally extended from the pump, said foot-platform having a clear space above it to permit an operator to stand thereon and having rigid floor-engaging anchoring means.

2. Asprayingapparatuscomprisingapump having operating means and rolling supporting means for engaging the floor, and an operators foot-platform having a clear space above it to permit an operator to stand thereon and slightly elevated above the floor-level and laterally extended from the pump, said foot-platform having a rigid non-rolling support.

3. Asprayingapparatuscomprisingapump having operating means and rolling supporting means for engaging the floor, and an operators foot-platform slightly elevated above the floor-level, said foot-platform having a clear space above it to permit an operator to stand thereon and being detachably secured to and laterally extended from the pump, and having a non-rolling support.

4. A paintspraying nozzle comprising a short casing having a screw-plug at each end in axial alinement, and an inlet branch 21 communicating with the side of the casing between the two plugs and having its outer end extending at an acute angle to receive a combined supply-pipe and handle, said acute angle being relative to a line passing through the two plugs, the forward screw-plug having a discharge-aperture 25 and provided with a partition or diaphragm 23 having perforations out of alinement with the aperture 25.

5. A spraying apparatus comprising a base and a pump thereon having operating means and rolling supporting means for engaging the floor, and an operators footplatform movably connected with said base and laterally extended therefrom and having a clear space above it to permit an operator to stand thereon and having rigid floor engaging means.

In testimony whereof I have affixed my signature in presence of two witnesses.
